Thank you Dan. It’s throwing a syntax error now. I can’t find anything wrong with the syntax though – is anything obvious sticking out please?
src=thisComp.layer(“Leader”);
delay = thisComp.layer(“Leader”).effect(“Delay”)(“Slider”);
d = delay*thisComp.frameDuration*(index – 1);
src.transform.xRotation.valueAtTime(time – d);
Error: missing ) after argument list
